Benefits of technology
The invention is a spiral air pressure spring that solves issues with traditional metal springs and gas springs. It has a pressure air containing cavity and at least one vent hole, making it possible to adjust hardness in real-time. It is simple in structure, convenient to process, and takes up a small space when compressed. This spring can be used for various applications such as mattress, sofa, and massage chair, and can be easily removed moisture to improve human body health. Additionally, it can be conveniently coiled for package, storage, and transportation.
Problems solved by technology
Such a compression spring is fixed and nonadjustable in elasticity after being formed and still takes up a large space after being compressed, and satisfactory comfortable level cannot be imparted to all the application areas when it is used for spring mattress and the like.
Gas spring has been designed, but it consists of a cylinder, a piston (push rod), an additional built-in spring and other parts, which leads to complex structure and high requirement on inter-part fitting; furthermore, the gas spring above is insufficient in deformation stroke and small in hardness adjustment range, and stills takes up a large space when not used.

embodiment 1
[0020]As shown in FIG. 1 and FIG. 2, a spiral air pressure spring described in the invention comprises a spring body, the spring body is formed by an air column 1 having a pressure air containing cavity, the air column 1 is spiral, one vent hole 2 communicated with the containing cavity is arranged on the air column 1, both inflation and deflation are completed by the vent hole 2, and there may also be two vent holes 2, for inflation and deflation respectively. The air column 1 is formed by a strip-shaped cylinder spirally, and the air column 1 is longitudinally arranged and provided with transverse and longitudinal air passages. The diameters of the upper and lower mouths of the air column 1 are smaller than the diameters of the spiral mouths in the middle, and the spiral mouths in the middle are consistent in diameter. Hard rings are lined at the upper and lower mouths of the air column 1, the spring body is sleeved with an outer cover, and both of the hard ring and the outer cove...

A spiral air pressure spring designed by the invention solves the technical problems of complex structure and low compressive strength in the current gas springs. The spiral air pressure spring comprises a spring body, and is characterized in that the spring body is formed by an air column having a pressure air containing cavity, the air column is spiral, and at least one vent hole communicated with the containing cavity is arranged on the air column. The hardness of the spiral air pressure spring is adjusted by filling pressure air, the spiral air pressure spring is particularly large in deformation stroke and good in transverse and longitudinal ventilation, is used for manufacturing mattress, sofa, massage chair, cushion and the like, and is easy to remove moisture so that the influence on human body health is eliminated; the spiral air pressure spring is convenient in hardness adjustment and wide in one-way deformation range, meets the demands on various occasions and can be adjusted in real time to enhance the comfortable level; in addition, the spiral air pressure spring is convenient for coiled package to save the transportation cost, and can be unfolded by inflation when used by a user.
Description
TECHNICAL FIELD[0001]The invention relates to the technical field of spring manufacturing, in particular to a spiral air pressure spring.BACKGROUND [0002]In terms of functionality, ‘springs’ can be classified in three categories including compression spring, torsion spring and tension spring, and common compression spring is formed by spirally coiling metal wires with strong elasticity, such as steel wires, and generates elasticity by means of their elastic deformation. Such a compression spring is fixed and nonadjustable in elasticity after being formed and still takes up a large space after being compressed, and satisfactory comfortable level cannot be imparted to all the application areas when it is used for spring mattress and the like. Gas spring has been designed, but it consists of a cylinder, a piston (push rod), an additional built-in spring and other parts, which leads to complex structure and high requirement on inter-part fitting; furthermore, the gas spring above is ins...
